10 | * lib/Compress/Zlib.pm -- 1.x Backward Compatability issues |
11 | gzclose - documented return value was wrong, should be 0 for ok. |
12 | gzflush - return value didn't match 1.x, should return 0 if ok. |
13 | [rt.cpan.org #29215] and Debian bug #440943 http://bugs.debian.org/440943 |

16 | |
17 | * Makefile.PL |
18 | Added INSTALLDIRS directive to install as a core module when built |
19 | on a perl >= 5.9. |
20 | |
21 | * t/03zlib-v1.t |
22 | Fixed crc32 and adler32 tests in to remove ascii assumption. |
23 | |
24 | * lib/Compress/Zlib.pm |
25 | Make gzreadline not support $/, just like in Compress::Zlib 1.x |

63 | 2.000_12 16 April 2006 |
64 | |
65 | * Fixed gzread to zap the output buffer to an empty string when zero |
66 | bytes are requested. This matches the behaviour of C::Z 1.x |
67 | |
68 | 2.000_11 10 April 2006 |
69 | |
70 | * No changes. |
71 | |
cb7abd7f |
72 | 2.000_10 13 March 2006 |
73 | |
74 | * Changed gzread so that its behaviour matches C::Z::gzread 1.x if it |
75 | is called after eof. In this case it will write an empty string |
76 | into the output parameter. This change is solely for backward |
77 | compatability reasons. |

135 | |
136 | * Integrate core change 25304 -- Symbian Update |
137 | |
138 | * Added libscan to Makefile.PL |
139 | |
5993747c |
140 | 1.37 - 12 August 2005 |
141 | |
142 | * Change to t/03examples.t for VMS from Abe Timmerman |
143 | |
144 | 1.36 - 3 August 2005 |
145 | |
146 | * Renamed zlib-src-1.2.3 to zlib-src to help VMS |
147 | |
148 | * Fixed Makefile.PL for VMS |
149 | |
150 | * Fixed t/03examples.t for VMS |

153 | |
06edba15 |
154 | 1.35 - 16 July 2005 |
155 | |
156 | * Updated zlib source to 1.2.3 |
157 | |
158 | * Fixed problem with where two calls to gzclose would hang the debugger. |
159 | See https://rt.cpan.org/Ticket/Display.html?id=13789 |
160 | |
161 | * Added code from Alexey Tourbin to use XSLoader when available, |
162 | and DynaLoader otherwise. |
163 | |
164 | * Documented that the compress & uncompress functions were not |
165 | the same as the Unix utilities of the same name. |
166 | |
167 | * Fixed 05gzsetp -- it left a temp file hanging around. |
168 | |

172 | |
173 | |
f4c6fd49 |
174 | 1.34 - 30 January 2005 |
175 | |
176 | * Fixed typo in the README |
177 | |
178 | * Fixed examples.t on Win32 where paths have embedded whitespace. |
179 | |
180 | * Fix for Cygwin and core integration from Jos I. Boumans |
181 | |
182 | * Upgrade zlib source to 1.2.2 |
183 | |
184 | 1.33 - 14 January 2004 |
185 | |
186 | * Reworked Makefile.PL to avoid creating a private copy of zlib. |
187 | This both simplifies the build, plus it makes life easier for VMS. |
188 | |
189 | * Patches for Makefile.PL to get it to work on VMS supplied by |
190 | Craig A. Berry. |
191 | |
192 | * memGunzip has very slow on FreeBSD. Turns out to be down to |
193 | the way realloc works on FreeBSD. Changed both inflate & deflate |
194 | to use exponentially increasing buffer sizes when they need to |
195 | realloc. Thanks to Peter Jeremy for the lowdown on FreeBSD |
196 | memory allocation. |
197 | |
198 | 1.32 - 26 November 2003 |
199 | |
200 | * Steve Hay reported a problem on rt.cpan.org with Windows and |
201 | MSCV++ 6.0 where the source from the zlib directory was getting |
202 | installed with the rest of the module. |
203 | https://rt.cpan.org/Ticket/Display.html?id=1741 |
204 | |
205 | This has been fixed by renaming the "zlib" directory to "zlib-src" |
206 | thus avoiding a conflict with the name of this Perl module. |
207 | |
208 | * Fixed a bug in the inflate method where the input buffer is an |
209 | lvalue (via substr). Problem & solution reported by Salvador Fandiqo. |
210 | |
211 | * Tightened up the logic in Makefile.PL when BUILD_ZLIB is |
212 | True. Issue spotted by Ralf S. Engelschall. |
213 | |
214 | 1.31 - 29 October 2003 |
215 | |
216 | * Reinstated the creation of .bak files - $^I seems to need a |
642e522c |
217 | backup file on Windows. For OpenVMS, the extenstion _bak is used. |
f4c6fd49 |
218 | |
219 | 1.30 - 28 October 2003 |
220 | |
221 | * Bundled a sub-set of the zlib source with the module and changed |
222 | the default make behaviour to build with the included zlib source. |
223 | The previous behaviour of using a pre-built zlib library is |
224 | still available for those that want it. |
225 | |
226 | * Added prototypes to the subs in Zlib.pm that didn't already have |
227 | them. Patch from Ed Avis. |
228 | |
229 | * No .bak files are created by Makefile.PL any more - this keep |
230 | distclean much happier. Patch suggested by Ed Avis. |
231 | This also fixes a similar problem reported by Dr. Martin Zinser |
232 | on OpenVMS. |
233 | |
234 | * Documentation for some of the gz functions updated. |
235 | |
236 | * Format strings modified in DispStream to keep OpenVMS happy. |
237 | Problem reported by Dr. Martin Zinser. |
238 | |
239 | |
240 | 1.22 - 17 June 2003 |
241 | |
242 | * Makefile.PL now displays a warning about not installing |
243 | Compress::Zlib via the CPAN shell. |
244 | |
245 | * Fix to allow intermingling of gzread & gzreadline - patch |
246 | supplied by Doug Perham. |
247 | |
248 | * memGunzip will silently now work if the gzip trailer is |
249 | missing. Some HTTP Origin Servers seem to leave it out. |
250 | |
251 | 1.21 - 28 April 2003 |
252 | |
253 | * Tests 148 & 150 from t/02zlib.t were failing on redhat 9. |
254 | |
255 | * Added a few words about the problems with Mac OS X to the README file. |
256 | |
257 | 1.20 - 4 April 2003 |
258 | |
259 | * Fixed bug in gzopen where $gzerrno wasn't being set correctly. |
260 | The symptom was $gzerrno was set to Z_MEM_ERROR although the file |
261 | was opened ok. If gzopen failed, $gzerrno was being set correctly. |
262 | This problem wasn't spotted before because the typical test |
263 | to determine whether gzopen passed or failed was to check its |
264 | return value. |
265 | |
266 | 1.19 - 31 October 2002 |
267 | |
268 | * fixed a problem with t/02zlib.t that was failing with redhat 8. |
269 | |
270 | 1.18 - 24 October 2002 |
271 | |
272 | * fixed a Win32 problem in t/02zlib.t by changing sysread to read. |
273 | |
274 | * zlib 1.0.5 & older doesn't have gzsetparams & gzeof. Added a new |
275 | variable to config.in to flag an old version of zlib. Split |
276 | out the tests for gzsetparams into t/05gzsetp.t |
277 | |
642e522c |
278 | 1.17 - 23 May 2002 |
f4c6fd49 |
279 | |
280 | * Moved the test to check the versions of libz & zlib.h into a separate |
281 | file and added troubleshooting notes to README. |
282 | |
283 | * In gzopen, only attempt to call "tell" for normal files. |
284 | |
642e522c |
285 | * Fixed to work in taint mode. |
286 | |
f4c6fd49 |
287 | * Broke changes out of README into Changes file. |
288 | |
289 | * Replaced internal use of Z_PARTIAL_FLUSH symbol with Z_SYNC_FLUSH. |
290 | zlib.h says /* will be removed, use Z_SYNC_FLUSH instead */ |
291 | |
f4c6fd49 |
292 | 1.16 - 13 December 2001 |
293 | |
294 | * Fixed bug in Makefile.PL that stopped "perl Makefile.PL PREFIX=..." |
295 | working. |
296 | |
297 | 1.15 - 4th December 2001 |
298 | |
299 | * Changes a few types to get the module to build on 64-bit Solaris |
300 | |
301 | * Changed the up/downgrade logic to default to the older constructs, and |
302 | to only call a downgrade if specifically requested. Some older versions |
303 | of Perl were having problems with the in-place edit. |
304 | |
305 | * added the new XS constant code. |
306 | |
307 | 1.14 - 27th August 2001 |
308 | |
309 | * Memory overwrite bug fixed in "inflate". Kudos to Rob Simons for |
310 | reporting the bug and to Anton Berezin for fixing it for me. |
311 | |
312 | 1.13 - 31st June 2001 |
313 | |
642e522c |
314 | * Make sure config.in is consistant when released. |
f4c6fd49 |
315 | |
316 | 1.12 - 28th April 2001 |
317 | |
318 | * Modified Makefile.PL to only enable the warnings pragma if |
319 | using perl 5.6.1 or better. |
320 | |
321 | 1.11 - 17th February 2001 |
322 | |
323 | * Added logic in Makefile.PL to toggle between using $^W and |
324 | the warnings pragma in the module. |
325 | |
326 | * The module, the examples & the test harness are now all strict |
327 | & warnings clean. |
328 | |
329 | 1.10 - 5th February 2001 |
330 | |
331 | * fixed a bug in memGunzip. Used Z_ERR instead of Z_DATA_ERROR. |
332 | |
333 | 1.09 - 15th January 2001 |
334 | |
335 | * Silenced a few compiler warnings. |
336 | |
337 | * Updated zlib home site in README & Zlib.pm to www.info-zip.org |
338 | |
339 | * Minor typo in Zlib.pm - a link used AUTHORS instead of AUTHOR |
340 | -- spotted by Frank Martini. |
341 | |
342 | * Mention Archive::Zip |
343 | |
344 | * added memGunzip. This is largely based on code provided by Jim Leonard. |
345 | |
346 | * $deflate->flush can now take an optional parameter. Valid |
347 | values are Z_NO_FLUSH, Z_PARTIAL_FLUSH, Z_SYNC_FLUSH, Z_FULL_FLUSH |
348 | and Z_FINISH. The default is Z_FINISH. |
349 | |
350 | 1.08 - 6 Jan 2000 |
351 | |
352 | * uncompress was clobbering its input parameter. Now it doesn't. |
353 | This bug was spotted by Deven T. Corzine. |
354 | |
355 | * If a variable that only ever contained a number was given |
356 | to compress or deflate, it would not be compressed properly. Now |
357 | it will be coerced to a string and then compressed. This bug |
358 | was spotted by Deven T. Corzine. |
359 | |
360 | 1.07 - 27 Nov 1999 |
361 | |
362 | * ANSI-ified the static functions in Zlib.xs |
363 | |
364 | * Added the ability to build zlib along with the module. |
365 | This feature is 90% based on a Makefile provided by Gurusamy |
366 | Sarathy. |
367 | |
368 | 1.06 - 20 Sep 1999 |
369 | |
370 | * Fixed a nasty problem where inflate could truncate the data |
371 | returned. Thanks to Douglas Thomson <dougt@mugc.cc.monash.edu.au> |
372 | for both spotting the problem and fixing the bug. |
373 | |
374 | * Added a note about the undocumented features in zlib that are |
375 | required when accessing zip files. |
376 | |
377 | * gzclose will now get called automatically when the gzip object is |
378 | destroyed. |
379 | |
380 | 1.05 - 3 June 1999 |
381 | |
382 | * Previous release used newSVpvn, which doesn't exist in 5.004_04 |
383 | or earlier. Changed to use newSVpv instead. |
384 | |
385 | * The module needs Perl 5.004 or better, so updated the version |
386 | checking in Zlib.pm and Makefile.PL |
387 | |
388 | 1.04 - 27 May 1999 |
389 | |
390 | * Bug 19990527.001: compress(undef) core dumps -- Fixed. |
391 | |
392 | 1.03 - 17 Mar 1999 |
393 | |
394 | * Updated to use the new PL_ symbols. |
395 | Means the module can be built with Perl 5.005_5* |
396 | |
397 | 1.02 - 31 Jan 1999 |
398 | |
399 | * The return codes for gzread, gzreadline and gzwrite were |
400 | documented incorrectly as returning a status code. |
401 | |
402 | * The test harness was missing a "gzclose". This caused problem |
403 | showed up on an amiga. Thanks to Erik van Roode for reporting |
404 | this one. |
405 | |
406 | * Patched zlib.t for OS/2. Thanks to Ilya Zakharevich for the patch. |
407 | |
408 | 1.01 - 23 Nov 1997 |
409 | |
410 | * A number of fixes to the test suite and the example scripts to |
411 | allow them to work under win32. All courtesy of Gurusamy |
412 | Sarathy. |
413 | |
414 | 1.00 - 14 Nov 1997 |
415 | |
416 | * Fixed crc32 & adler32. They were very broken. |
417 | |
418 | * The following functions can now take a scalar reference in |
419 | place of a scalar for their buffer parameters: |
420 | |
421 | compress |
422 | uncompress |
423 | deflate |
424 | inflate |
425 | crc32 |
426 | adler32 |
427 | |
428 | This should mean applications that make use of the module don't |
429 | have to copy large buffers around. |
430 | |
431 | |
432 | * Normally the inflate method consumes I<all> of the input buffer |
433 | before returning. The exception to this is when inflate detects |
434 | the end of the stream (Z_STREAM_END). In this case the input |
435 | buffer need not be completely consumed. To allow processing of |
436 | file formats that embed a deflation stream (e.g. zip, gzip), |
437 | the inflate method now sets the buffer parameter to be what |
438 | remains after inflation. |
439 | |
440 | When the return status is Z_STREAM_END, it will be what remains |
441 | of the buffer (if any) after deflation. When the status is Z_OK |
442 | it will be an empty string. |
443 | |
444 | This change means that the buffer parameter must be a lvalue. |
445 | |
446 | * Fixed crc32 and adler32. They were both very broken. |
447 | |
448 | * Added the Compress::Zlib::memGzip function. |
449 | |
450 | 0.5 - Confirmed that no changes were necessary for zlib 1.0.3, or 1.0.4. |
451 | |
452 | The optional parameters for deflateInit and inflateInit can now |
453 | be specified as an associative array in addition to a reference |
454 | to an associative array. They can also accept the -Name |
455 | syntax. |
456 | |
457 | gzopen can now optionally take a reference to an open |
458 | filehandle in place of a filename. In this case it will call |
459 | gzdopen. |
460 | |
461 | Added gzstream example script. |
462 | |
463 | 0.4 - Upgrade to support zlib 0.99 |
464 | |
465 | Added dictionary interface. |
466 | |
467 | Fixed bug in gzreadline - previously it would keep returning |
468 | the same buffer. This bug was reported by Helmut Jarausch |
469 | |
470 | Removed dependency to zutil.h and so dropped support for |
471 | |
472 | DEF_MEM_LEVEL (use MAX_MEM_LEVEL instead) |
473 | DEF_WBITS (use MAX_WBITS instead) |
474 | |
475 | 0.3 - Added prototype specification. |
476 | |
477 | 0.2 - Fixed a minor allocation problem in Zlib.xs |
478 | |
479 | 0.1 - first alpha release. 2nd October 1995 |
